System-dependent behaviour of the loop is specified by declarative description of the domain (essentially descriptions of available actions), and statement of the goal. We evaluate the design of this framework on examples taken from resource construction in Utility Computing environments, and discuss the challenges we have encountered. Our implementation utilizes external components such as \emph{MBP}, a \emph{PDDL}-conform planner, and \emph{Triana}, a workflow specification and execution framework. An alternative approach involving \emph{BPEL4WS} is discussed.}, language = {en} } @inproceedings{AndrzejakKondoYi2010, author = {Andrzejak, Artur and Kondo, Derrick and Yi, Sangho}, title = {Decision Model for Cloud Computing under SLA Constraints}, booktitle = {Modeling, Analysis \& Simulation of Computer and Telecommunication Systems (MASCOTS), 2010 IEEE International Symposium on}, publisher = {IEEE}, doi = {10.1109/MASCOTS.2010.34}, pages = {257 -- 266}, year = {2010}, language = {en} } @inproceedings{AndrzejakKondoAnderson2010, author = {Andrzejak, Artur and Kondo, Derrick and Anderson, David}, title = {Exploiting non-dedicated resources for cloud computing}, booktitle = {12th IEEE/IFIP Network Operations \& Management Symposium (NOMS 2010)}, address = {Osaka, Japan}, doi = {10.1109/NOMS.2010.5488488}, pages = {341 -- 348}, year = {2010}, language = {en} } @inproceedings{AndrzejakZeinalipourDikaiakos2009, author = {Andrzejak, Artur and Zeinalipour, Demetris and Dikaiakos, Marios}, title = {Improving the Dependability of Grids via Short-Term Failure Predictions}, booktitle = {CoreGRID Workshop at EuroPAR 2009}, address = {Delft, Netherlands}, year = {2009}, language = {en} } @inproceedings{CasanovasAlonsoTorresetal.2009, author = {Casanovas, Ada and Alonso, Javier and Torres, Jordi and Andrzejak, Artur}, title = {Work in Progress: Building a Distributed Generic Stress Tool for Server Performance and Behavior Analysis}, booktitle = {ICAS}, publisher = {IEEE Computer Society}, doi = {10.1109/ICAS.2009.53}, pages = {342 -- 345}, year = {2009}, language = {en} } @inproceedings{AndrzejakKondoAnderson2008, author = {Andrzejak, Artur and Kondo, Derrick and Anderson, David}, title = {Ensuring Collective Availability in Volatile Resource Pools via Forecasting}, booktitle = {19th IEEE/IFIP Distributed Systems: Operations and Management (DSOM-2008)}, address = {Samos Island, Greece}, pages = {149 -- 161}, year = {2008}, language = {en} } @misc{AndrzejakReinefeldSchintkeetal.2008, author = {Andrzejak, Artur and Reinefeld, Alexander and Schintke, Florian and Sch{\"u}tt, Thorsten and Mastroianni, Carlo and Fragopoulou, Paraskevi and Kondo, Derrick and Malecot, Paul and Cosmin Silaghi, Gheorghe and Moura Silva, Luis and Trunfio, Paolo and Zeinalipour-Yazti, Demetris and Zimeo, Eugenio}, title = {Grid Architectural Issues: State-of-the-art and Future Trends}, number = {WHP-0004}, publisher = {Institute on Architectural Issues: Scalability, Dependability, Adaptability, CoreGRID - Network of Excellence}, year = {2008}, language = {en} } @inproceedings{YiKondoAndrzejak2010, author = {Yi, Sangho and Kondo, Derrick and Andrzejak, Artur}, title = {Reducing Costs of Spot Instances via Checkpointing in the Amazon Elastic Compute Cloud}, booktitle = {Cloud Computing (CLOUD), 2010 IEEE 3rd International Conference on}, doi = {10.1109/CLOUD.2010.35}, pages = {236 -- 243}, year = {2010}, language = {en} } @inproceedings{Andrzejak2009, author = {Andrzejak, Artur}, title = {Generic Self-Healing via Rejuvenation: Challenges, Status Quo, and Solutions}, booktitle = {Workshop on Architectures and Languages for Self-Managing Distributed Systems (SelfMan@SASO)}, address = {San Francisco, California, USA}, year = {2009}, language = {en} }
